Applicationaied .my 1e, 1912. serial No. 710,479.

To all whom z't may concern Be it known that I, THOMAS Hour, a subject of the King of Great Britain and Ireland, residing'at Victoria Mills, Walshaw, Bury, county of Lancaster, England, cotton manufacturer, have invented improvements in the Manufacture of Woven Fabrics, of which the following is a specification.

This invention relates to improvements in the manufacture of quilts or bed spreads. In this invention the quilt is woven with one coarse weft and two coarse warps which are preferably of finer counts than the weft; the warps used are of equal counts, but the cloth may be woven with warps of unequal counts.

In this invention one of the warps known as the' back warp, contains only half the number of ends contained by the other Warp, which is known as the face warp, that is, one third of the yarn comes from the back warp and the remaining two thirds comes from the face warp. The back warp is heavily weighted and the face warp lightly: Weighted, thus giving the groundwork of the quilt a ribbed appearance.

For the ground weave of the quilt all the face Warp 1s lifted and all the back warp is left down on odd numbered picks, and all the back Warp is lifted and the face warp left down on even numbered picks.

For the figure weave all odd numbered picks are the same as for the ground weave, but on even numbered picks those threads which are required to figure are lifted up; these threads come from the face warp, and at the same time all the back warps are'lifted. lllhe back warp is drawn in through healds, which are worked by atappet, while the face warp is drawn through mails and Worked by a jacquard. The mails are knotte'd above the comber boards, and these lift on all odd numbered picks, While the jacquard for figuring purposes lifts on even numbered picks. rlwo threads from the face warp and one thread from the back warp are drawn in each dent of the reed. Two threads from the face warp may also be drawn through each mail, and thus allow a mounting to be used containing only half the number of mounting Ythreads compared to the threads in the face warp.

0n the accompanying drawing Figure l represents the order of lifting for the ground weave of cloth, Fig. 2 represents the order of lifting for the figure Weave of cloth (the 'end View of warp threads.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l.; A raised-warp figured fabrichaving a.

single coarse weft and finer face and back warps, of which the face is composed of twice as many ends as said back warp; the fabric having a ribbed ground showing alternately at the back and front thereof and formed by all the ends of the face warp passing over the weft and all the ends of the back vwarp passing under the weft on all odd numbered picks, and all the ends of the face warp passing under the weft and all the ends of the back warp passing over the weft on all even numbered picks the raised figures being formed by the ends of the face warps fioating over the weft for a' number of picks, and the ends of the back warp at such figures continuing to pass collectively under and over the weft picks upon which the face warp is floated.

2. A raised-figured fabric having a single coarse weft and face and back warps,of which the face warp is composed of a greater number of threads than said back warp, the fabric having a ribbed ground formed by all the raised ends of the face warp and showing alternately at the front and the back there of, all the ends of the back warp being left down on all odd numbered picks, and all the ends of the face warp being left down while all the ends of the back warp on evennumbered picks are lifted; the raised figures being formed by floating the ends of the face warp over the wefts for a number of picks and the ends of the back warp at such figure continuingy to pass collectively under and over the weft picks upon which the face ,warp is floated.

3. A raised-figured fabric having a single coarse weft; and face and back warps of which said face warp is composed of twice as many threads as said back warp, the fabric having a ribbed ground formed by all lll@ the raised ends of the face Warp and showing pass collectively under and over the weft alternately at the front and the back thereof, picks upon which the face Warp is fioated.

all the ends of the back Warp being left down In testimony whereof, I have signed my on all odd-numbered picks and all the ends name to this specification, in the presence of 5 of the face warp 'with all the ends of the two subscribing witnesses.

back warp on even-numbered picks being left up; the raised figures being formed by THOMAS HOLT' floating the ends of the face Warp over the Witnesses: wefts for a number of picks and the ends of THoMAs PREscoTT,

10 the back warp at such figure continuing to HAROLD WALKER.
